EARLIER: Police are investigating after a fire in a vacant house in Golden Square.

Firefighters were sent to the Olympic Parade property about 12.45pm after receiving multiple calls.

Kangaroo Flat Fire Brigade fourth lieutenant James O'Brien said the fire started in a bedroom of the vacant and derelict house, and it was partially alight when crews arrived.

He said thanks to a quick response by the CFA, crews were able to minimise the damage to about 15 per cent of the house.

Neighbour Darren Bradley said the house had been vacant for about eight years, with teenagers often using it for parties at night.
